MHT CET 2026 19th April Morning Shift | Capacitor Question 4 | Physics

A parallel plate capacitor of capacitance 'C' is connected to a battery and charged to a potential 'V'. Another capacitor of capacitance '$3C$' is charged to a potential '$3V$'. The charging battery is then disconnected and both the capacitors are connected in parallel to each other such that positive terminal of one is connected to negative terminal of the other. The final energy of the configuration is

$1.5\,CV^2$

$6.5\,CV^2$

$8.0\,CV^2$

A capacitor of unknown capacity is connected across a battery of V volt. The charge stored in it is Q coulomb. When potential across the capacitor is reduced by $\mathrm{V}_1$ volt, the charge stored in it becomes $\mathrm{Q}_1$ coulomb. The potential V is

$\frac{\mathrm{QV}_1}{\mathrm{Q}-\mathrm{Q}_1}$

$\frac{Q_1 V_1}{Q+Q_1}$

$\frac{Q_1}{Q}$
